I know a bunch of you guys are in the software business, so you should know how much marketing stuff is thrown around these days. I know the MFR's claim the spectrum origination is such it makes it appear brighter from being more saturated, but that doesn't really make sense if you look into it far enough. More than likely, the main thing is just that the LED lamps are producing closer lumens to their ratings and holding them longer, since they don't lose brightness like regular lamps.A quickie from the WIKI....
HSL and HSV do not qualify because many spectral colors lie rather far from its gamut.
Samples (allegedly in sRGB) currently rely on Wikipedia data which sometimes use poor, unprofessional sources, misinterpretation of sources, or occasionally contain original researches.
Values for the hue (HSL and HSV or an extrapolation, where necessary) currently rely on Wikipedia data which are prone to miscalculation and other irregularities. Also note that RGB is not an absolute color space, and certain specific standard (such as sRGB) is necessary to map RGB hues to near-spectral colors.
